To all whom it may concern:

Be it known that I, MAX RACHLIN, a citizen of Russia, and resident ofthe city of New York, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Window Screens,

in parallel planes from one another, so that Insects may readily enterthe room between the overlapping portions of the screen fabrics. It hasbeen proposed heretofore to provide means'for preventing passage ofinsects between the, frames. This means is usually in the form of avertically extending 'bar which forces the fabric of one frame againstthe inner vertical member or stile of the other frame. This bar hasheretofore been rigidly attached at both of its ends to the windowscreen, so that, when the sections of the latter are moved in relationto one another for purposes of adjustment,.the said bar, in bearingagainst one of the screen fabrics, is apt to injure the latter,attention being called to the fact that the fabrics bulge in time, sothat not only will the said bar wear away the fabric by friction buttear the same in case it bulges out excessively.

The main object'of the present invention is to provide 'means forforcing the screen fabric of one frame section into engagement with theinner stile member of the other section, which overcomes thedifficulties above referred to. 1

Another object of the invention is to provide a device of the characterdiscribed which is simple in construction, efficient in operation,durable in use'and which is capab e of manufacture on a commercialscale,

or in other words one which is not so difficult to make as to be beyondthe reasonable cost of such a contrivance.

With these and other objects in view,

which will more fully appear as the nature. of the invention is betterunderstood, the

same consists in the combination, arrangement and construction of partshereinafter described, pointexl out in the appended claims andillustrated in the accompanying drawings, it being understood that manychanges may be made in the size and proportion of the several parts anddetails of construction within the scope of the appended claims, withoutdeparting from the spirit or sacrificing any of the advantages oftheinvention.

A. few of "the many possible embodiments of theinvention are,illustrated in the accompanying drawings, in which Figure 1 is a frontelevation of a window screen constructed in accordance with the presentinvention; Fig. 2, is a section taken on line 2-2 of 'Fig. 1, on alarger scale; Fig. 3 is a section taken on line 3-3 of Fig.

1, also on a larger scale; Fig. tis a section 7 taken on line 4.4= ofFig. 1, also on a larger scale; Fig. 5 is an elevation similar to theoneshown in Fig. 1 of the drawings of a modification of the invention; Fig.6 is a section taken on line 6-6 of Fig. 5, on a larger scale; Fig. 7 isan elevation'similar to the one shown in Fig. 1 of the drawings of afurther modification of the invention; Fig.

8 is a section taken online 88 of Fig.

on a larger scale; and Fig. 9 is a section similar to the one shown inFig. 8, with certain elements of the device in other positlons.

Generallyspeaking, the invention consists in pivoting to one of thehorizontal rails of a window screen frame section, in spaced relationfrom but in alignment withthe inner stile of the said frame section, oneend of a bar, the other end of which is adapted to be engaged withanddisengaged from the opposite horizontal rail of the other framesection; said bar bein adapted to bear against the screen fabric of thelast-mentioned, frame section.

Referring now first to Figs. 1 to 4, in-' elusive, of the drawings, thenumeral 10 indicates one of the sliding sections of the window screen,and the numeral 11 the companion section thereof. The section 10comprises two stiles 12 and 13, connected by a lower horizontal rail 14'and an upper horizontal rail'15'. In a similar manner the frame section11 comprises two stiles 16 and-17, connected by a lower horizontal rail'18 and an upper horizontal rail 19. Across these two frame sections arestretched screen fabrics 20 and 20, respectively. The two frame sectionsmay be made of any suitable material and may be of any suitableconstruction, the horizontal rails of one frame section overlappingthose of the other section and being slidably connected. In the caseillustrated in the drawings, the stiles and rails of each frame sectionare'provided with channel beads 21 througho'utl their lengths, thescreen fabric ofeach frame section having its marginsextending into thechannels of the said section and being held in place by a locking member22, inserted into the channels. It is obvious that any other suitableconstruction may be provided for fastening the screen fabrics to theframe sections, the one herein described being disclosed for purposes ofillustration only. It is, however, essential that the stile 13 of theframe section 10 be provided with ahead 21, projecting toward the screenfab-- ric 20' of the frame section 11 into contact with the fabric fromthe lower rail 18 to the upper rail 19 of the last-mentioned framesection. As appears from Figs. 2 to 4, inclusive, of the drawings, thescreen fabrics of the'two frame sections are spaced from one another,they extending in parallel vertical planes.

To the lower rail 14 of the frame section 10 is attached in any suitablemanner a clip 23, extending around the lower rail 18 of the framesection 11, the arrangement being such that'the said clip does notinterfere tion 11 on the frame section 10. To the clip is pivoted at 24a bar 25, preferably,

' made of metal.

This bar is bent at its lower end inwardly toward the fabric 20 ontheframe section 11 and extends in contact with the said fabric to theupper rail 19 of the frame section 11. At its upper end the said bar isbent outwards, as shownat 26, and thence upwards as indicated at 27., Afinger piece 28 is attached to the bar. The portion 27 of the bar isadapted-to be seated in a longitudinal groove 29 in the u per rail 19 ofthe frame section 11, the sai groove extending from stile to stile ofsaid frame section. The bar 25 is somewhat springy, so that, when it isdisengaged from the groove 29', it springs away from the fabric 20', asshown in dotted lines in Fig. 3 of the drawith.

en the elements are in the positions shown in full lines in Figs. 1 and3 of the drawings, the bar 25 contacts throughout its length with thefabric 20 of the frame section 11, forcing the same into engagement withthe stile 13 of the frame section 10, and thereby preventing the passageof'insects between the fabrics of the frame sections into the room.Whenever it is intended to adjust the screen, that is to say to slideone section thereof upon the other, the bar 25 is taken hold of by thefinger piece 28 and shifted around its pivot 24 into the position shownin dotted lines in Fig. 1 of the drawings. moves away, owing to itsresiliency, from the fabric 20, so that a sliding movement of the twoframes in relation to one another will be permitted without the barwearing away the fabric 20.

The modification illustrated in Figs. 5 and 6 of the drawings differsfrom the one above described in that the bar, which forces the fabric ofone frame section against the stile of the other frame section, isdetachably carried by the frame section 11. This bar is indicated in thedrawings by the numeral 30, it being, preferably, made of a yieldingmaterial. Adjacent its ends the said bar is provided with finger pieces31, which are shown as being made integral with the bar, although thisis not essential. The lower rail 18' and the upper rail 19' of the framesection 11 are provided each with a longitudinal groove 29. in which theends of the bar 30 are adapted to be seated.

When the bar is in position upon the frame section 11', it forces thefabric 20 When thebar is then released, it

of the frame section 11' into engagement moved from the frame section11, to be put again in position thereon after "the adjustment has beenmade.

The modification illustrated in Figs. 7 to 9, inclusive, of the drawingsdiffers from the one described in connection with Figs. 1 to 4,inclusive, in that, instead of one clip, there are two clips provided.One of these clips, denoted by the numeral 32, is attached to the lowerrail 14' of the frame section 10", and the other one, denoted by thenumeral 33-, is secured to the upper rail 15 of the frame section 10".These clips extend around the upper and lower rails of the frame section11", permitting of a sliding movement of the two frame sections inrelation to one another. Each of'these clips is which is slidably fitteda bar 35, adapted to bear against the screen fabric 20 of the framesection 11 and to force the same against the inner stile 13" of theframe section 10". A spring 36 is interposed between each end of the bar35 and the adjacentrail of the frame section 11", said springs having atendency to force the bar 35 out of engagement from the screen fabric20'.

Upon each clip is p-ivot'a'lly mounted a lock-,

If it is intended to adjust the frame secprovided with side flanges 34,between.

fabric 20', against the action of the springs tions of the screen inrelation to one another, the locking members 37 are shifted around theirpivots soils to be disenga ed from the bar 35. The springs 36 are t usfree to act, freeing the' bar 35 from the screenfabric. After the properadjustment has been made, the locking members are moved on their pivotsinto engagement with the bar 35, causing the same to bear against thescreen fabric of the frame section 11".

While herein specific constructions have been described for permittingadjustment of the screen frames in relation to one another, any othersmay be used without departing from the invention which lies main-f ly inthe provision of a bar adapted to force the screen fabric of one frameagainst the inner stile of the other frame, said bar being disengageablefrom said screen fabric so as .not to bear against the same whenadjustment of the frame sections is to be made.

What I claim is 1. A window screen comprising two frames slidably joinedtogether, each frame consisting of two stiles connected by atop rail andby a bottom rail and a screen fabric stretched across the same; a clipsecured to the bottom rail, of one of said frames in alignment with itsinner stile, said clip extending around thebottom rail of the otherframe, a bar pivoted to the free end i of said clip adapted to bearagainst the screen fabric of said last-mentioned frame and to force saidfabric into engagement with the stile of the-frame to which said clip issecured, and coacting means on the free end of said bar and the top railof the frame against the fabric of which it bears for separablyfastening the free end of said bar to the last-mentioned top rail.

2. A window screen comprising two frames slidably joined together, eachframe consisting of two stiles connected by a top rail and by a bottomrail and a screen fabric stretched across the same, 'a clip secured tothe bottom rail of one. of said frames in alignment with its innerstile, said clip extending around the bottom rail of the other frame,the top rail of said last-mentioned frame being provided with a lonitudinal groove, and a bar pivoted to the rec end of said cli adapted tobear against the screen fabric of said last-mentioned frame and to forcesaid fabric into engagement with the stile of the frame to which saidclip is secured when the free end of said baris seated in said groove.

3. In a window screen according to claim 1, said bar being made ofyielding material so that it springs away from the adjacent screenfabric when said coacting means are disengaged.

4. In a window screen according to claim 2, said bar being made ofyielding material so that it springs away from the jacent screen fabricwhen its free end is disengaged from said groove.

5. A window screen comprising two frames slidably joined together, eachframe consisting of two stiles connected by a top rail and by a bottomrail and a screen fabric stretched across the same, and a bar adapted tobear against the screen fabric of on of said frames and to force saidfabric into engagement with the stile of the other frame, said bar beingdisengageable from said screen fabricto-permit adjustment of said framesin relation to one another.
